12 the trigger, 13 the barrel,f14 lthe receiver, 15 the hammerand 16 the breechfb'olt of a firearm, all of which parts vmay beaconstructed in any desired lmanner anc of proper material. A breech-bolt stop .17 Vis movably mounted inthe side of the receiver to engage a shouldei18`on the breech-bolt 16 and hold it in its rearward position when the magazine is not in its proper place in the handle, the magazine being constructed so that its end 19` will engage the stop and holdit inits inoperative position when-the magazine is in .itsl proper position. The construction. and operation vof the 'parts y above described will be readilyA understoodY shown in the drawings the stop 17 will .be forcedby its springinto position to intercept forward movemento'f the breech-bolt.l

, A. magazine releasing. rod is movably mounted with respectV to the magazineyto effect the releaseof said'magazine, this rod preferably being mounted lon the handle, and in the structure herein shown a releasingrod case 2O is securedto the side ofthe handle 10, preferably as bymeansof a plate 21formed integral with the case, which plate issecured to the `side of the handle-in any The case and plate are preferably `formedof a single piece of sheet metal bent to shape, this piece of sheet metal being formed and cut to providea flap that is bent preferably into round for-m to constitute a spring case 22, and as shown lin Figs. 5` and 6 ofl the'drawings.

A releasing rod V23 vis inclosed case 201for sliding movement therein.A This rod is constructed, preferably from a piece of sheet metal and with a .boulder V.2li to receive ajreleasing rodfactuatine- .Sivr'ing 25 that is' Seated abone end against. this .Shoulder .and at its other @ed against an overturned lip 26 at the ond .of the Spring oase 22- .A hook 2'? is foimedpat leasing rod to engage a 111th@ rrferrod one end fthe r releasing rod .holder '28- form 'of construction this holder comprises la shoulder inthe side edge .of-1.a '.S1Qt'29 gxtendine downwardly .state .that whenV the magazine is moved from 'the position.

within theV lengthwise ico from l the upper. Vend l lthe end ofthe rod nection with the above of a magazine 30, the part of the slot below this shoulder constituting a releasing notch 3l. The lower end of the releasing rod comprisesamagazineV catch release, in the form of construction herein shown, this release being formed as a cam 32vto engage a nose 33 on the end of a catch'lever 34, preferably mounted on the side of the handle and as shown in Fig. l of the drawings. One end of this lever is formed into a thumb piece 35 that projects to the outer surface of one of the grip pieces 36, and a lug comprising oil` from the holder28. In the structure herein shown a releasing cam 404 is formed on the side of the follower to operate the hook 27 and discngage it from the holder 28.

It will be seen from thev drawings in conthe successive feeding movements of the cartridges into the barrel,lthe follower will travel upwardlyk under the force of its spring 41 in a manner that will be readily under- Y stood. kWhen the last cartridge 44 inthe magazine is forced into the barrel by the forward movement of the breech-bolt, thc follower will b e moved byits spring against the bottom of the breech-bolt, and in this position the cam 40 will bein close proXimity to the hook 27.

At the next firingraction,

vcaused by the hammer 15 when released b' f the trigger 12, the breech-bolt will be forced back-k wardly by the exploding gases Ybeyond the follower, releasing the latter that will be forced upwardly until stopped by lips 42 at themouth of the magazine. In this final upward movement of the follower'the cam 40 will engagel the hook 27 and release it from the holder 28, upon which release the spring 25 will ,move the rod-23 quickly downward, causing the cam 32 to engage the nosey 33 of the catch lever34 and move the catch lug 37 from within the h ole38.l The magazine being thus released will drop from its chamber within the handle, in which -movement the breech-bolt stop 17 will be released and moved into the path of the breechfbolt which it will catch and hold in its backward position. It will be understood that this entire actiontakesy place very quickly and Vin the time between the release of the follower by the breech-bolt and the completion of the backward movement of the breech-bolt.

When the next magazine, with a cartridge or hook 27 and thrust itV description that in or cartridges therein, is manually forced to place in the handle, the lips 42 on the magazine will engage the stop 17 releasing it from the breech-bolt and the latter will move forward under the force of its spring carrying with it theuppermost cartridge in the magazine and forcing it into'the barrel.

lIn this inward movement of themagazine the holder 28 thereon will engage the hook 27 and move the releasing rod 23l upwardly and from'engagement with the catch lever, whereupon the latter spring to encrage the catch 37 with thevmagazine to hold it in place. y
